I've ran into the same problem, and it's been about 15hrs before I realize it, now I can't really load a save file because that would be a more than 30hrs of repeated gameplay and it's disgusting. Yet I've tried to progress the game anyway, I've finished the Ragnar and London quest as well, but now I'm stuck since the Yorkshire require 190lv and no chapter 6 quests are in my list.
Really a shame. I was hoping that the 1.04 patch would fix this problem and yet it didn't. Sad.

I have the same issue. Having reported to the Ubisoft support but it didn't seem work, they haven't reached me since asking me to confirm if the ''an island of eels'' is in my quest list. which it did appear in my completed list. Think about it I first finished this quest with 30 or 35 strength and now I'm like 120. Really desperate if I have to replay that many content again.

@elocnasty Seems not. Actually I did go back to play an other game saving for last few weeks and have surpassed the broken one in progress now that I'm already doing Yorkshire quests.
Still it's a really unpleasant experience to go through all these quests again.:(
Btw my Ubisoft Support case has never been of any use.
My friend, if you are still stuck with this problem, I don't think it would be a prior bug to be patched. That 1.04 update didn't patch it, so didn't 1.10, it's literally a waste of time wishing they'd solve it immediately. If you want to play the rest of the game I'd recommend you to start over again. Surly it would be more efficient than wasting time waiting for patches.

@guest-z8acpuei Same problem, and it's been more than 20hrs before I realize that I hadn't really make an allegiance with Grantebridge, and that island of eel quest is in my completed list as well. I've not saved the game since 4hrs into it, so it's even not possible for me to load an earlier save file. Really hope for an update or a fix to resolve this issue. I'm stuck in chapter 5 and can find no way into further gameplay.
